Jonathan Lawlor commented on HBASE-13262:
-----------------------------------------
Good catch! Took a quick look and it seems to be related to the change in the
default caching value from HBASE-11544 when coupled with the change in the
default max result size from HBASE-12976. I was actually able to reproduce this
issue in branch-1.0 by tweeking the caching and max result size to be equal to
the defaults that are present in branch-1+. Specifically, the following
configuration also produced issues for me in branch-1.0:
{code}
Scan scan = new Scan();
scan.setMaxResultSize(2 * 1024 * 1024);
scan.setCaching(Integer.MAX_VALUE);
...
{code}
(Note that to run the scan with this configuraiton you must remove the
ArrayList presizing that is performed in RSRpcServices on line 2055. The
caching value is used to presize the array and thus you will likely run into
OOME if you do not remove the presizing when running this configuration).
As to why this error is occuring, I am not sure yet, but I thought this may
shed some light on it.

> Project: HBase
> Issue Type: Bug
> Components: Client
> Affects Versions: 2.0.0, 1.1.0
> Environment: Single node, pseduo-distributed 1.1.0-SNAPSHOT
> Reporter: Josh Elser
> Assignee: Josh Elser
> Priority: Blocker
> Fix For: 2.0.0, 1.1.0

>
> Tried to write a simple Java client again 1.1.0-SNAPSHOT.
> * Write 1M rows, each row with 1 family, and 10 qualifiers (values [0-9]),
> for a total of 10M cells written
> * Read back the data from the table, ensure I saw 10M cells
> Running it against {{04ac1891}} (and earlier) yesterday, I would get ~20% of
> the actual rows. Running against 1.0.0, returns all 10M records as expected.
> [Code I was
> running|https://github.com/joshelser/hbase-hwhat/blob/master/src/main/java/hbase/HBaseTest.java]
> for the curious.
